reset: imx: Add support for i.MX8MP reset controller

Add support for i.MX8MP reset controller, it has same reset IP inside
as the other iMX7 and iMX8M variants but with different module layout.

Inspired from counterpart Linux kernel v6.8-rc3 driver:
drivers/reset/reset-imx7.c. Use last Linux kernel driver reference
commit bad8a8afe19f ("reset: Explicitly include correct DT includes").
